Hydrogen and Battery Trains: Siemens Redefines Sustainable Travel in Germany

Diesel trains are being replaced by cutting-edge hydrogen and battery-powered alternatives in Germany’s rail networks. Siemens Mobility’s groundbreaking Mireo trains promise to redefine eco-friendly travel while slashing emissions.

Siemens Mobility has announced yet another milestone in sustainable transportation with the launch of its Mireo Plus H hydrogen trains and Mireo Plus B battery trains. Their debut is set for the December 15, 2024 timetable change, starting operations in Bavaria and Berlin-Brandenburg, Germany.

Hydrogen-Powered Mireo Plus H Begins Service

The Mireo Plus H hydrogen train is at the forefront of Germany’s rail modernization. According to Railway-News, seven units will be operated by Niederbarnimer Eisenbahn Betriebsgesellschaft on the Heidekrautbahn line in Berlin-Brandenburg. These trains are expected to save 1.1 million liters of diesel annually, cutting CO2 emissions by 3,000 tons. Using locally produced hydrogen, the trains emit only water vapor and reuse braking energy to maximize efficiency.

In Bavaria, the Mireo Plus H will replace diesel trains operated by Bayrische Regiobahn (BRB). Initially running in the East Allgäu-Lechfeld network, the trains will later serve the Ammersee-Altmühltal network, aligning with Bavaria’s plan to eliminate diesel propulsion by 2040 and transforming regional railways into sustainable transit systems.

André Rodenbeck, CEO Rolling Stock at Siemens Mobility, said, "This transition will reduce CO2 emissions and provide passengers in Germany with climate-friendly, powerful, and comfortable trains."

The hydrogen-powered train boasts a 1,200-kilometer range and a top speed of 160 km/h, powered by a 1.7 MW H2 traction system. These state-of-the-art features ensure quiet, efficient, and eco-friendly operations while reducing Germany’s carbon footprint.

Siemens Mobility confirmed on December 12 that it has received the Authorisation to Place on the Market (APOM) in Germany from the European Union Agency for Railways (ERA) for its Mireo Plus H hydrogen multiple-units.//t.co/3VbBDqdteo

Battery Trains Revolutionize the East Brandenburg Network

In Brandenburg, the rollout of 31 Mireo Plus B battery trains on the East Brandenburg network is to eliminate 4.4 million liters of diesel consumption annually, as IRJ reports. The battery-electric trains have a range exceeding 120 kilometers, entirely removing local CO2 emissions and reducing broader emissions by 11,500 tons per year. These two-car trains are designed with accessibility and passenger comfort in mind. Each train offers 127 seats, 12 multi-use spaces, free WiFi, and 60 power sockets, making them ideal for modern commuter needs. The inclusion of spacious family areas and bicycle storage shows Siemens’ focus on inclusive travel solutions.

This rollout is expected to significantly enhance connectivity in the region while reinforcing Germany’s commitment to climate-friendly transportation. Niederbarnimer Eisenbahn Betriebsgesellschaft has already begun integrating the new trains into its fleet, with full operation expected by mid-2025.

Cutting-Edge Railcars for Danube-Isar and Regensburg Networks

Siemens is also delivering new trains for other key networks. According to the press release from Siemens Mobility, the Danube-Isar network will benefit from 25 Desiro HC double-decker trains and six Mireo trains, tailored to serve the Munich-to-Nuremberg Airport Express. These trains feature high-frequency glass for improved mobile reception, flexible seating configurations, and ample luggage space.

Meanwhile, 21 Mireo trains will join the Regensburg-Danube Valley network, serving routes such as RE lines 50 and 51. Enhanced features, including WiFi and optimized seating, ensure a superior travel experience for passengers traveling between Nuremberg, Regensburg, and Plattling. A unique highlight of the Danube-Isar network is its ability to accommodate increased capacity. Up to three Desiro HC trains can run coupled between Munich and Landshut, offering flexibility for high-demand periods while maintaining passenger comfort.

Environmental Impact and Future Goals

Siemens’ Mireo platforms prioritize sustainability. The hydrogen and battery trains not only reduce reliance on fossil fuels but also highlight the potential for energy-efficient, low-emission rail travel. The Mireo Plus H trains will play a significant role in achieving Germany’s climate goals, particularly in regions like Bavaria, where the shift away from diesel is a priority. The integration of real-time diagnostics and modular designs further ensures high availability and simplified maintenance for operators. The company’s focus on hydrogen and battery trains shows its vision for a greener, more sustainable future in passenger transportation.
